Persistent bacteriuria in a dog caused by Salmonella enterica subspecies enterica serovar Indiana

Abstract

An 11-year-old male intact Kromfohrländer dog was presented with vomiting, inappetence and progressive lethargy. Polypoid cystitis and acute prostatitis were suspected. Bacterial culture of the urine revealed a bacteriuria with Salmonella enterica subspecies enterica serovar Indiana (referred to as S Indiana). Although the general condition improved with antibiotic treatment (enrofloxacin; 10 mg/kg/day orally and osaterone acetate; 3.75 mg/kg/day orally), S Indiana was still present in the dog's urine four weeks later. Repeated treatment with antibiotics (amoxicillin-clavulanic acid, 18 mg/kg orally) resulted in full recovery of the dog but S Indiana was still present in the urine. Clinical improvement under antibiotic treatment indicates that S Indiana was probably the causative agent of the diagnosed cystitis and prostatitis, but long-known chronic diseases may have favoured the colonisation with this pathogen and its persistence. To the authors’ knowledge, this is the first report of bacteriuria associated with S Indiana in a dog.
